Does anyone know what this is please!

I have a very slight drip of oil from the front right side of my 182 it's running down the part pictured which is visible through the front tow hook hole! Thanks in advance

Does the oil smell like cat piss?

Thanks Dan any idea where the leak could be coming from and is there anything I can get to easily to take a look?
